Ateliosis is a medical term used to describe a condition of incomplete or arrested growth. There are several synonyms for ateliosis, including dwarfism, microsomia, hypoplasia, and stunted growth. Dwarfism is the most commonly used term and refers to a condition in which an individual's growth is severely restricted, resulting in a shorter height than average. Microsomia means small body, and hypoplasia refers to underdevelopment of body tissues or organs. Stunted growth is a more general term that describes a delay or interruption in the normal growth process. These synonyms are used interchangeably depending on the specific context, but they all describe a condition in which an individual experiences restricted growth due to various factors.
